Finally I rig the Code Red 11 mts lefting out the last pulley and all seems and feel ok. Even I think I don't need a new extension. Sail is very power and well balanced. I rig in a Gaastra 550 Gold Series (IMCS37) instead the Red Line 550 ( IMCS 34) but the sail looks and feel ok for me.

Thanks to all of you....

What about if I leave the first out? I alredy have a crank ( chinook) for the Neilpryde extension but I think that maybe is better to left the first shave out ( considering that the pressure of the line is not even, and the second sheave is more centered with the center of effort of the tack pulley.......

I will try both ways on Saturday.

Any of you try with the Neilpride X6 extension? has the same nš of pulleys ( 2) but in rigth angle to the sail pulley position, this may alllow to share the load in better way.....

Roger is spot on.
We have Overdrives from 10 down to 5.5and a 4.6 CR and they will always load up the last 2 sheaves.
I think the extreme downhaul on these sails make it difficult for all the sheaves to share the load evenly.Dont get me wrong we think Overdrives are a great sail ,and the CR as well but they need serious downhaul.(Dont all cammed sails?)
We use a crank type downhaul for these sails,overtension,then back off 10mm till the pulleys sit almost parallel to the extension.This would not be possible without a crank type downhaul tool.

Hi michelb,
Try to leave out one of the middle sheaves (rollers) in your sails tack fitting.
I just rigged a Severne NCX 7.5m2 the other day, and I had no problems by using the outside pulleys (sheaves) and skipping one of the inside (the 2nd) pulleys.
If you (and Mim) are not using a downhauling tool (crank type works best for me) you really might want to consider the damage you may be doing to your lower back by trying to pull all that tension with your lower back muscles.
Put all the load on an easy to use tool and save your back.
The tool makes "micro adjusting" much easier as well.
Hope this helps,

I will try as you said lefting out a roller in the sail pulley, i think maybe is easy if i left the last one out.... let's try.

Thanks for your suggestion.

I do not have experience with the Overdrive or Code Red...

My Severne NCX has also a pulley with 4 rollers and my old extension had only two rollers and a brake (it means one was missing on the extension). I have to say that NCX is not easy to downhaul and there is a lot of force needed to get it rigged properly.

I used to left out the second roller on the pulley...try it, pull it down with a screw drived or with a help of a harness hook and pull hard!!!...I believe you can get it done.

Wish you a good luck.
Ciao Michal.

Again in english....

Severne sails ( Overdrive and Code red has 4 rollers in the tack of the sail. My neilPryde extension has only 2 rollers plus the cleat.
On saturday I try to rig the CR11 mts 2007 with a Nautix 3 rollers + cleat but the first 2 rollers did not doing force. the last 2 rollers did all the force, then the sail can not be rigged too.

Here in Chile there is no one Severne extension and our dealer can have something for December or January. I need to sail from now to this date and I can not figure how to rig the beautiful sail I have......
